Current Behavior

Nx crashes with an error.

Expected Behavior

Nx should run without an error.

Steps to Reproduce

1. git clone git@github.com:IsaacScript/isaacscript.git
2. cd isaacscript
3. git checkout a2ab4fdc399d00931561557e806bdee2f7ebcd74
4. yarn
5. npx nx report

You will get the following error:

+ npx nx run-many --target=build --all
/home/runner/work/isaacscript/isaacscript/node_modules/nx/node_modules/yargs/node_modules/cliui/build/index.cjs:293
const wrap = require('wrap-ansi');
             ^

Instead change the require of index.js in /home/runner/work/isaacscript/isaacscript/node_modules/nx/node_modules/yargs/node_modules/cliui/build/index.cjs to a dynamic import() which is available in all CommonJS modules.

Additional Information

You can see the error in the following GitHub Action run:
https://github.com/IsaacScript/isaacscript/actions/runs/5084290118/jobs/9136389446

The error seems to be because nx uses cliui, which tries to import wrap-ansi. wrap-ansi is supposed to be a CommonJS module, but is instead an ES module, causing the error.

Thus, I believe that the issue will occur with any brand new installations of nx.

[AgentEnder]

This error doesn't really make sense, cliui does depend on wrap-ansi, but at v7, which is still CJS. v8 of wrap-ansi has been around for a decent chunk of time now, and I've not seen this reported before. Can you try regenerating your lockfile? I'm wondering if something went wrong when installing packages.

[Zamiell]

Yes, I've tried nuking node_modules directory + yarn.lock file multiple times, and the error persists. You can follow the reproduction steps that I've listed above in the OP to confirm. (Feel free to delete the yarn.lock file after cloning the repo.)

[AgentEnder]

After regenerating the lockfile locally, it seemed to work for me. You can see the changes here: IsaacScript/isaacscript#57

[AgentEnder]

To be clear, I was able to repro before regenerating the lockfile. I'm not sure how it was deduping v8 of wrap-ansi, that was invalid and npm ls highlighted it as such.

It kind of seems like a package manager bug, but a nasty one that I'm not sure what would have caused.

[Zamiell]

After merging your PR, we can still see the exact same error in CI: https://github.com/IsaacScript/isaacscript/actions/runs/5094206401/jobs/9157731090

[AgentEnder]

Yeah, I saw that but can't really speak to it...

If you pull down the commit SHA referenced in this issue, and run install its broken.
If you run rm -rf yarn.lock node_modules, and then run yarn it works as it should.
If you run rm -rf node_modules, and then run yarn --frozen-lockfile its broken again. This is essentially what CI is doing.

Like I said, this seems like a really nasty issue with the package manager, its not something thats coming from Nx's side of things. This pattern reproduced for your repo on your CI, my machine, and a colleague's, but I don't think there is much more assistance we can provide. I'd recommend opening an issue on yarn's repo, and perhaps investigate updating some of your other packages.

Thanks for taking the time to look into it Ender.

For others reading this thread, I was able to solve the problem by upgrading from Yarn 1 to Yarn 3. (I'm not using plug-n-play, i.e. I'm still using the node_modules directory.)

I was on Node 20 but rolled back to Node 18, still using Yarn 1 and seems to work.

I also have nvm installed and use this, I noticed even though I switched to Node 18 I notice nx was still trying to use Node 20.

Deleted all node_modules and yarn.lock and reopened the terminal and yarn to reinstall and then nx worked.
